PENNSYLVANIA, ASSIGNORS TO PENNSYLVANIA CRUSHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEVT YORK ORUSHER Application filed October 18, 1927.

Our invention relates more particularly to single roll crushers intended for heavy duty and designed to operate upon large masses of rock, coal, and the like, and where the shock attending the crushing roll when striking these masses and crowding them against the anvil formed by the breaker-plate must be resisted by the side frames of the machine.

In general, our structure follows the lines of single roll crushers of the usual type, but the feature of our invention is the provision of side frames preferably of all-steel construction; such side frames being in the form of integral castings or fabricated structures of large Size, spaced apart laterally and connected together by heavy tie members which may be bolted or otherwise secured to said side frame to form the complete crusher structure.

In our improved structure, the side frames in side elevation are substantially U-shape in in drawing up these bolts to theirfinal positions respectively, in order to avoid setting up strainsin the lower portion of the side frames which might cause the latter to give away under stress of heavy duty, and the main object of our invention is to provide an improved construction whereby the space or recess ineach side frame above the upper bearing cap may be closed and the end porture and avoid the setting up of any strains tions of the side frames flanking such open space properly connected together in a manner that will insure a stable and rigid strucin any portion. of said side frames.

A further ObJGCt of our invention 1s to pro vide a filling piece for the space or recess of Serial No. 226,841;

space; said bolts being threaded at each end for the reception of nuts which may be drawn up independently and insure a rigid connection of the parts without setting up strains.

These and other features of our invention are more fully described hereinafter; reference being had to the accompanying drawings, in which Figure 1, is a longitudinal sectional elevation of one form of single roll crusher to Which our invention may be applied; the side frame only being shown by full lines, while the connecting or tie members and crushing mechanism are shown by broken lines.

Fig. 2, is a side elevation of a side frame for single roll crushers constructed in accordance with our invention.

Fig. 3, is a plan view of the side frame, partly in section on the line IIIIII, Fig. 2.

Fig. 4, is an end view of the filling piece employed with the side frames, and t Fig. 5, is a vertical sectional view of. the filling piece, taken on the line V-V, Fig. 2. Fig. 2 shows in elevation a complete side fram-e illustrating our improved construction; being indicated generally at 1. In the form disclosed in the drawings, such side frames may comprise an integral casting of steel, with t0p,bottom, and end flanges externally disposed, and indicated at 2, 3, 4

said side frame between said recess and said end flanges being indicated at 1 and 1', respectively. The lower portion of the recess is curved, as indicated at 10*, and an extension 11, integral with the side frame receives the usual bushing 11 providing the lower bearin for the shaft 12, of the crushing roll 13. A bearing cap 14, of any usual type is provided for the shaft and its bushing, and above this bearing cap, the recess 10 provides an open space between the portions 1 and 1", of such side frame, which space receives a filling block, indicated at 15, and forming the subject of our invention.

The oppositely disposed walls 10 of this space are properly faced and shouldered at 10 for the reception of this filler number 15, shown more particularly in Figs. 3, 4 and 5; a portion of said filling member fitting between said walls 10 and closing the upper portion of the space 10 between the end portions 1 and 1 of the side frame. In order that the filling members of the respective side frames may be properly secured in place and perform the desired function, we provide bolts 16, which pass through the same and through heavy ears or bosses 17 and 18, formed on the outer surface of the end portions 1 and 1 of said side frames adjacent the walls 10 of the space 10; such bolts being held in place by nuts 19, one on each end of each of said bolts. These nuts may be longitudinally grooved so as to be taken up by a spanner wrench of the hook type.

The filler members 15 may be and preferably are in the form of hollow steel castings, which are open onthe underside, and more p grticularly illustrated in Figs. 3, 4 and 5.

my are preferably of the shape shown, having side walls 20 and 20", the former flush with the outer surface of the flanges 2; end walls 21 an internal reinforcing rib 22 .parallel to the side walls, and a cross rib 22 The end walls of the filler member rest on the shoulders 10 and engage the walls 10 of the space 10; filling the upper portion of the space between the end portion 1 and 1 of the side frames above the bearing, so that the nuts 19 on the securing bolts 16 may be set up very tightly withoutproducing any strain or tension in any portion of said side frames. The wall 20 of the filling member depends below the wall 20 and is provided with end PIQJGCtiOIlS or flanges 22 vertically disposed, and arranged to engage the inner wall of the side frames; the surface 22 of said end flanges engaging the inner surfaces of the walls of the, end portions 1 and 1", adjacent to the walls 1O flanking said space 10. The filling block15 and bolt 16 constitute a combined compression and tension member for each side frame which prevents the setting up of strains practicallyunavoidable with the ordinary structures bolted in the manner above referred to.

In the final condition of use, each side frame of a single roll crusher built in accordance with our invention, is a substantially single, unitary, structure without any tendency to produce the stresses and strains common to the side frames employed with the usual type of single roll crushers. At the same time the filler members which we provide may be readily removed to gain access to the crushing roll or the bearings, and when the bearing caps 14 of the latter are removed, the shaft, together with the crusher roll, may be readily lifted out.

By preference, the filler members carry detachable wear plates 23 secured to their inner face, (indicated by broken lines, Figs. 1 and 5,) which plates overhang the ends of the crusher roll so that any small particles accompanying the larger size rock or other material being crushed will be diverted from the bearings, and directed into the crushing zone. Dust guards 24 are preferably disposed externally of and beneath the filler blocks and above the upper bearing cap, and may be carried by the depending wall 20 of the filler blocks; recesses 25, for the reception of holding screws 26, being shown in Fig. 2.

The greatest shock to the side frames occurs when huge rock masses are caught between the crushing roll and the anvil, and it is at this time that the maximum strength of the side frame is called into use. The necessity of removing the crushing roll and shaft unit under modern practice makes the provision of a recess intermediate the ends of the said side frames unavoidable, and the filling members fitting within the recesses between said end portions and properly secured thereto provide a rigid structure and a substantially unitary frame, well able to resist the stress to which crushers of this character are subjected without danger of breakage.
